I have a chow/lab mix. About 5-6 years old. We got her from a shelter about 1.5 years ago. She is a good natured dog and very playful and excitable.
My problem is when someone new comes over, which is not often, she is very friendly, brings them toys and things like that. She will even lay be them when she calms down. But after about 30-45 minutes she will try to attack their feet.
She has never hurt anyone and she only goes after there shoes and can be distracted but she continues to do it. She commonly plays with our feet and we are usually the ones to initiate it, she especially loves my mothers large slippers.
She never growls or barks when doing this to guests or us.
Has anyone ever had something like this before?
I worry that she will hurt someone. Do you think it is just because we play with her with our feet? Does anyone have any advice?
